Success stories in India’s edtech sector follow a familiar script: rapid growth, aggressive funding, and often, equally rapid optimization. But every once in a while, a different kind of story emerges. One that begins not with capital but in the classroom. Alkh Pandey’s journey with Physics Wallah sits somewhere in this space, where scale is built not overnight but lesson by lesson. In November 2025, the journey reached an important milestone. PhysicsWallah’s stock market debut has spawned two new Indian billionaires. Founder and Chief Executive Officer (CEO) Alakh Pandey, then 33, became the country’s youngest billionaire, while his business partner Prateek Bob, 37, also joined the list. The Noida-based company listed at a 42 percent premium to its initial public offering price, raising about $390 million. Forbes. On one level, this is a story about market success. Elsewhere, it’s about a teacher who chose an unconventional path and built a company that now reaches millions of students across India.
A teacher before an entrepreneur
Alkh Pandey didn’t start out with a company in mind. He started in the classroom. Raised in Prayagraj, Uttar Pradesh, he began teaching early, offering private tutoring while still in school. Later, as an engineering student, he continued teaching, but eventually dropped out in his third year. The decision to drop out of college did not mark the end of his educational journey. In 2014, he started a YouTube channel “Physics Wallah Alkh Pandey”, which offers free physics lessons. Over time, the channel grew to around 14 million subscribers. His teaching style was informal and direct. He used humor, relatable examples and even visual cues like tattoos to explain complex concepts. This approach helped him establish a strong rapport with students, many of whom were preparing for competitive exams but could not afford expensive coaching.
Building Physics Wallah
The company took shape in 2020 when Pandey partnered with Prateek Bob, who had developed an e-learning application called PenPencil. Their shared idea was simple: Let’s make education affordable and accessible, and at scale. Physics Wallah began by offering courses for engineering and medical entrance exams. Over time, it spread to other areas of school-level education and test preparation. This platform works through online and offline centers. Growth has been aided by stable funding. The company has raised Rs 9 billion in 2022 and Rs 18.6 billion in 2024 from investors such as Westbridge Capital and Lightspeed Venture Partners. It has also expanded through acquisitions. In 2022, PhysicsWallah acquired UAE-based Knowledge Planet to reach out to the Indian diaspora. A year later, it bought a 50 percent stake in Kerala-based Xylem Learning for about Rs 5 billion. In 2025, it held a 40 percent stake in a test preparation firm focused on Public Service Commission examinations.
A sector formed by rising and falling.
Pandey’s success comes at a time when India’s edtech sector is still adjusting after a period. The rise of companies like Byju’s and Unacademy showed how quickly the price could rise. It also showed how quickly they could fall. This context takes a closer look at Physiyatwallah’s journey. The question is not just how it grew, but whether it can sustain that growth.
Beyond the milestone
For Alkh Pandey, the label of “youngest billionaire” marks a moment, not an outcome. His identity is linked to teaching, even as a physicist working at the national level. The company now operates over 200 YouTube channels with a combined subscriber base of nearly 100 million. It continues to use the proceeds from its public offering to expand its physical presence and invest in technology and acquisitions.Physics Wallah started with the idea of making quality education affordable and widely accessible. Students will not measure this trophy by market listings or prices. They will measure this by whether the lessons are accessible, whether the cost remains within reach, and whether the platform delivers what it initially promised. In that sense, the journey from college dropout to billionaire is only part of the story. The more consequential part is what happens next, in classrooms that may never know the details of the market, but will feel the consequences of their decisions.
